Teens may curate their Instagram accounts, but there appears to be no stopping the bad advertisements on the platform. David Teicher, chief content officer of Brand Innovators, tweeted an Instagram ad he saw that included the R-word on May 30.

The ad was for “Hustle Castle,” a video game that uses the offensive word to describe players on the first level.

The studio behind the game, My.com, told Digiday after the publication of this article that the ads have been removed.

“This was not intentional by our Moscow based User Acquisition team. This was a poor judgment call without the proper knowledge of the language and disconnected from the local market. We apologize for the offense and will take steps to improve our advertisement choices for our entertainment applications,” said My.com’s head of public relations Maikel van Dijk.

The “Hustle Castle” ad “violates our grammar and profanity policy and has been disabled,” an Instagram spokesperson said. “Ads on Facebook and Instagram must, at the very base level, comply with our Community Standards. Our Ads Policies build on that benchmark, and are stricter.”

Instagram is contributing to the spread of these offensive ads. Yet the platform continues to operate without much scrutiny or criticism. Even amid the crisis facing its parent company Facebook, Instagram remains beloved among users and marketers. Instagram is expected to grow nearly 11 percent to $8.06 billion in ad revenue in 2018,which is about 16.5 percent of Facebook’s total revenue, according to eMarketer.

“If Instagram were a TV show, it would’ve been canceled,” said an ad industry executive. “If Instagram were a person, there’d be an angry Twitter mob. But it’s Instagram, so it gets a pass.”

Problematic ads on Instagram, or elsewhere on the internet, are far from a new issue. Programmatic advertising and self-serve platforms are part of the problem. There’s also human error. It was a Snap Inc. employee who approved a Snap ad that asked, “Would you rather: Slap Rihanna or punch Chris Brown?” While high-profile celebrities like Chrissy Teigen abandoned the platform in the aftermath, advertisers, for the most part, have continued to buy on Snapchat. Same goes for Instagram.

Instagram offers a reporting feature to help police its platform. In just two taps, a user can express their concern about the nature of an ad. The first reason is, “I find it offensive.” There are no other options to clarify or add context once users select that response.

Facebook’s team of moderators receive those reports. In the wake of Russian interference in the 2016 U.S. election via Facebook’s platforms, Facebook CEO Mark Zuckerberg declared that his company would hire more people for security and content moderation, and the staff would total 20,000 by the end of the year. According to an Instagram spokesperson, the company is adding more than 1,000 people specifically to the global ads review team. Facebook also has been investing more in machine learning and other technological solutions to help flag and take down ads.

“There’s a perception that Facebook has been burning in ashes, but that Instagram is untouchable,” Eric Schiffer, CEO of ReputationManagementConsultants.com and DigitalMarketing.com, told Digiday last month. “All it requires is one high-profile incident.”
